A chesty cough, also known as a productive cough, is characterised by the presence of thick secretions or phlegm in the airways. It is often the result of irritation or inflammation of the nose, throat or upper respiratory tract. Unlike a dry cough, which is irritating and does not produce mucus, a productive cough is accompanied by sputum or phlegm.
When the airways are inflamed, the body produces mucus to protect them from irritants or infections. This build-up of mucus can lead to a feeling of congestion in the chest and throat, which causes a productive cough. This cough is actually the body’s natural mechanism for expelling excess secretions and impurities from the airways, which helps to clear the airways and make breathing more easily.
